Patent number: 11605304Abstract: A computer-implemented method for learning a policy for selection of an associative topic, which can be used in a dialog system, is described. The method includes obtaining a policy base that indicates a topic transition from a source topic to a destination topic and a short-term reward for the topic transition, by analyzing data from a corpus. The short-term reward may be defined as probability of associating a positive response. The method also includes calculating an expected long-term reward for the topic transition using the short-term reward for the topic transition with taking into account a discounted reward for a subsequent topic transition. The method further includes generating a policy using the policy base and the expected long-term reward for the topic transition. The policy indicates selection of the destination topic for the source topic as an associative topic for a current topic.Type: GrantFiled: March 6, 2017Date of Patent: March 14, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Hiroshi Kanayama, Akira Koseki, Toshiro Takase

Patent number: 11580373Abstract: Computations in Artificial neural networks (ANNs) are accomplished using simple processing units, called neurons, with data embodied by the connections between neurons, called synapses, and by the strength of these connections, the synaptic weights. Crossbar arrays may be used to represent one layer of the ANN with Non-Volatile Memory (NVM) elements at each crosspoint, where the conductance of the NVM elements may be used to encode the synaptic weights, and a highly parallel current summation on the array achieves a weighted sum operation that is representative of the values of the output neurons. A method is outlined to transfer such neuron values from the outputs of one array to the inputs of a second array with no need for global clock synchronization, irrespective of the distances between the arrays, and to use such values at the next array, and/or to convert such values into digital bits at the next array.Type: GrantFiled: January 20, 2017Date of Patent: February 14, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Geoffrey W Burr, Pritish Narayanan

Patent number: 11580411Abstract: Systems are provided for implementing a hardware accelerator. The hardware accelerator emulate a stochastic neural network, and includes a first memristor crossbar array, and a second memristor crossbar array. The first memristor crossbar array can be programmed to calculate node values of the neural network. The nodes values can be calculated in accordance with rules to reduce an energy function associated with the neural network. The second memristor crossbar array is coupled to the first memristor crossbar array and programmed to introduce noise signals into the neural network. The noise signals can be introduced such that the energy function associated with the neural network converges towards a global minimum and modifies the calculated node values.Type: GrantFiled: December 18, 2018Date of Patent: February 14, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Suhas Kumar, Thomas Van Vaerenbergh, John Paul Strachan

Patent number: 11567930Abstract: Methods and systems are disclosed for data retrieval, from databases to clients, in an environment requiring runtime authorization. In response to a request for T data records, a learning module provides a prediction R of a suitable number of data records to retrieve from a database. Following retrieval of R records or record identifiers, authorization is sought from an authorization service, resulting in A of the records being authorized. The A authorized records are returned to the requesting client, and, if more records are needed, T is decremented and the cycle is repeated. A performance notification is provided to the learning module for training, with respect to providing values of prediction R. The performance notification can be based on a measure of authorization service performance, the number A of authorized records, latency, communication or resource costs, a measure of resource congestion, or other parameters. Variants are disclosed.Type: GrantFiled: April 25, 2017Date of Patent: January 31, 2023Assignee: SAP SEInventors: Apoorv Bhargava, Madathiveetil Bipin, Markus Schmidt-Karaca, Ismail Basha, Gonda Marcusse, Vishnu Kare, Praveen Kumar, Neenu Vincent

Patent number: 11526744Abstract: Methods, apparatuses, and embodiments related to a technique for monitoring construction of a structure. In an example, a robot with a sensor, such as a LIDAR device, enters a building and obtains sensor readings of the building. The sensor data is analyzed and components related to the building are identified. The components are mapped to corresponding components of an architect's three dimensional design of the building, and the installation of the components is checked for accuracy. When a discrepancy above a certain threshold is detected, an error is flagged and project managers are notified. Construction progress updates do not give credit for completed construction that includes an error, resulting in improved accuracy progress updates and corresponding improved accuracy for project schedule and cost estimates.Type: GrantFiled: May 31, 2017Date of Patent: December 13, 2022Assignee: Doxel, Inc.Inventors: Saurabh Ladha, Robin Singh

Patent number: 11521106Abstract: This disclosure relates to learning with transformed data such as determining multiple training samples from multiple data samples. Each of the multiple data samples comprises one or more feature values and a label that classifies that data sample. A processor determines each of the multiple training samples by randomly selecting a subset of the multiple data samples, and combining the feature values of the data samples of the subset based on the label of each of the data samples of the subset. Since the training samples are combinations of randomly chosen data samples, the training samples can be provided to third parties without disclosing the actual training data. This is an advantage over existing methods in cases where the data is confidential and should therefore not be shared with a learner of a classifier, for example.Type: GrantFiled: October 23, 2015Date of Patent: December 6, 2022Assignee: National ICT Australia LimitedInventors: Richard Nock, Giorgio Patrini, Tiberio Caetano
